Disclosed herein are methods and systems for painting driving markings invisible in visible light spectrum, comprising generating driving assistance markings expressing driving information relating to one or more road segments, computing instructions for painting the driving assistance markings on one or more elements of the road segment(s) using one or more paint material(s) characterized by: (1) reflecting light in a visible light spectral range deviating less than a first value from the visible light spectral range reflected by a surface of the element(s) and (2) reflecting light in an infrared spectral range deviating more than a second value from the infrared spectral range reflected by the surface of the element(s), and outputting the painting instructions for applying the one or more paint materials on the element(s) according to the instructions such that the driving assistance markings are visible in the infrared spectrum and significantly invisible in the visible spectrum.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The method of claim 1, wherein the first value equals 20% and the second value equals 25%.
3. The method of claim 1, wherein the driving assistance markings are directed to support at least one automatic vehicular system of at last one vehicle, the at least one automatic vehicular system receives at least one image of the at least one element painted with the driving assistance markings captured by at least one imaging sensor adapted to operate in the infrared light spectral range.
4. The method of claim 1, wherein the driving information comprising information relating to at least one transportation infrastructure object located in the at least one road segment and/or in at least one subsequent road segment.
5. The method of claim 1, wherein the driving information comprising guiding markings to assist at least one automatic vehicular control system of at least one vehicle to conduct at least one control operation of the at least one vehicle.
6. The method of claim 1, wherein the at least one element is a member of a group consisting of: a surface of the at least one road segment, a colored mark printed on the at least one road segment and an infrastructure object located in proximity to the at least one road segment.
7. The method of claim 1, wherein the painting instruction comprise instructions for painting the driving assistance markings using the at least one paint material closely around at least one visible marking of the at least one road segment.
8. The method of claim 1, wherein the painting instruction comprise instructions for applying the at least one paint material over a painted surface of the at least one element.
9. The method of claim 1, wherein the painting instruction comprise instructions for applying the at least one paint material in conjunction with at least another one paint material used to paint a surface of the at least one element.
10. The method of claim 1, wherein the infrared light spectral range characteristic to the at least one paint material is in a range of near infrared (NIR) having a wavelength in a range of 750-1400 nanometers.
11. The method of claim 1, wherein the infrared light spectral range characteristic to the at least one paint material is in a range of short wave infrared (SWIR) having a wavelength in a range of 1400-3000 nanometers.
14. The method of claim 13, wherein the driving assistance markings are painted closely around at least one visible marking of the at least one road segment using the at least one paint material.
15. The method of claim 13, wherein the at least one paint material painting is applied over a painted surface of the at least one element.
16. The method of claim 13, wherein the at least one paint material painting is applied in conjunction with at least another one paint material used to paint a surface of the at least one element.
